The spacing and character of Fig. 2 is a fragmentary enlarged section taken apertures or perforations of the paneling illusl5 on the line 2 2 of Fig. 1. trated in Figs. 4, 5 and 6, however, permits of Fig. 3 is an enlarged section taken on the line the cutting therefrom of doors or panels of di- 3-3 of Fig. 1; mensions varying widely both in width and also Fig. 4 is a view similar to Fig. 1 of a modificain length, or in a plurality of dimensions. tion according to the invention; Inthe construction illustrated in Fig. 7, the 40 Fig. 5 is a section taken on the line of Stiles, designated 2|, are provided inwardly Fig. 4; e extended tongues 22 and the exterior or top and Fig. 6 is a View similar to Fig 4 of a second bottom rails 23 are provided with similar exmodication according to the invention; and I tendmg tongues 24' The tongues are adapted to n 7 y i r cve, f third support the reinforcing laminated panels 25 45 nezigfon' z'fvvnelrilnre oyin; 31e prnrlges which have their exterior surfaces ilush with the of the modification illustrated in Fig 1 surfaces of the stile 2| and exterior rails 23. Se-

Referring to the drawing in detail', it will be cured between the Opposlte tongues 22 of the stiles 2|, in the same manner in which th l seen that in each of the modifications illustrated I2 are secured between the Stiles H in th; g 50 in the drawing, the paneling consists of a pair struction of Figs. 1, 2 and 3, are the intermediate of surface panels Secured t0 Opposite Sides 0f a or interior rails 26 which like the rails l2 of the core or frame whichis provided with apertures or above described construction, are uniformly perforations disposed in a particular manner, as spaced from one another at dimensions less than 55 hereinafter described, which adapts the paneling their width. The thickness of the intermediate 55 rails 26 is equal to the thickness of the tongues 22 and 24. It will thus be seen that the frame or core of the construction illustrated in Fig. 7 is formed by the stiles 2|, rails 23 and 26, and the reinforcing laminated panels 25. The surface panels I0 are secured to this frame or core in the same manner as the panels l0 are'secured to the frames or cores in the embodiments illustrated in Figs. 1 to 6, inclusive, as described above.

As may readily be seen from Figs. l to 3, inclusive, the paneling illustrated therein may be cut to lengths varying within rather wide limits to produce a door or another panel having a solid top and bottom and surfaces provided by 'the rails I2 at either end. If the width of the rails I2, for instance, is three inches and the width of the apertures by the adjacent rails is two inches, then the length of the panel cut from the paneling maybe varied in increments of one inch with the provision of a solid surface at each end of the cut panel. For instance, if it be desired to reduce the length of the panel illustrated in Fig. 1 by one inch, each end thereof may have onehalf inch cut therefrom. If it be desired to reduce the length of the panel two inches, one inch may be cut from each end of the panel. If it be desired to reduce the length of the panel four inches,two inches may be cut from each end of the panel with the result that one inch of each end of the rail I2 shall remain to provide a solid surface at each end of the panel. If it be desired to reduce the length by five inches however, the five inches may be out from one end with the result that the end rail at each end of the resulting panel shall be intact, or three inches in Width. /f/

In the embodiment of Fig. 7, it is merely necessary, in reducing the length of the paneling, that any cuts made therein shall pass through the rails 23, the tongue 24 thereof and the intermedi- I ate rails 2li.y

In the constructions of Figs. 4, 5 and 6, asy

pointed out above, the dimensions of the panels cut from the paneling may be varied both in length and also in width. For instance, if the Width and length of the apertures l5 be one inch or the diameter of the aperture lI6 be one inch and the centers of these apertures be spaced at three inches, then the nearest adjacent portions of the respective apertures shall be spaced.

two inches and by following the procedure explained above in the description of the construcillustrated in Figs. 4, 5 and 6 may be Varied in increments of one inch or less.

In each of the above cases, the variation of the variable dimension or dimensions, of the panels or doors, cut from the panel in nowise affects the edge surfaces of the nished door or panel and in nowise detracts from the insulating capacity of the nished door or panel or the strength thereof. In any of the constructions illustrated in the drawing and described above, it is, however, necessary, in the attainment of this invention, that the apertures or open spaces in the frame orcore of the paneling be spaced apart by solid material a distance greater than the greatest dimension.

It is, of course, to be understood that the above described structure is merely illustrative and in nowise limiting and that I desire to comprehend all modifications included Within the scope of.

the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A warp resistant panel construction, severable in small increments to form panels of various predetermined dimensions, and comprising, a

core provided with uniformly spaced similar ap- 1 ldistances greater than their dimensions in that direction, the size of the apertures and the distances of separation between the apertures being in whole number units of measurement.

3. A warp resistant panel construction provided with internal dead air spaces and severable in small increments to form panels of varying predetermined dimensions in at least one direction, said panel construction comprising an apertured core having continuous surface panels secured thereto, said core comprising a core of sheet form provided with similar geometric apertures uniformly spaced in each directiorn at distances greater than their dimension in that direction,

the size of the apertures and the distances of separation between the apertures being in whole number units of measurement.
